The Lowdown
Alright, Rusty here. Let’s have a good look at what’s on the table for the next couple of weeks.
The surf window opens straight away with a decent pulse of SW groundswell. We’ve got a consistent run of clean, lined-up waves, but this is serious juice – most of the time it’s over 5 ft and often pushing past 7 ft, so this isn’t a beginner’s playground. The standout is Lakey Pipe (Lakai-Pipe). It’s a reef setup, so those long-period SW swells are going to wrap in perfectly. The water’s sitting at 80°F, which is about normal for this time of year. The energy is cranked – we’re seeing combined swell energy values in the thousands, like 2192 on Thursday morning. That’s strong, powerful water moving through.
Thursday the 10th kicks off with a solid 6 ft SSW swell at 15 seconds, with a clean cross-off wind from the SE. The sets will have real push and the reef will shape them up nicely. Through Friday the 11th, it’s a similar vibe: 7 ft SW at 16 seconds. The wind stays light and cross-off, so the faces will be clean. Crowds are often here – you won’t have it to yourself, but the quality makes it worth sharing.
Saturday the 12th still has good energy, with 5 ft SW swell and clean conditions, but it drops a notch. Sunday the 13th is a ripper – a 6 ft SW groundswell at 18 seconds in the morning, then it jumps to 8 ft in the afternoon. That afternoon bump has combined energy of 3778 – that’s a lot of power. This is expert territory. The reef will handle it, but you need to know what you’re doing.
We stay in the 6 ft to 7 ft range through the middle of the following week, with consistent cross-off winds. The swell direction sits right in the SW to SSW sweet spot for this break. Light winds on the 15th and 16th make for really appealing sessions. The 17th and 18th keep pumping, with clean morning glass and solid energy.
Heading into the third week, it doesn’t let up. The 20th of September has a 5 ft SW groundswell at 17 seconds with light SE winds – that’s a quality morning. Then on the 23rd we see a standout jump: 7 ft SSW at 17 seconds, combined energy of 3116. That’s the biggest, most powerful swell of the whole run, and it’s aimed right at the reef. The 24th keeps that energy going with 7 ft to 8 ft SSW swells. This whole run into late September is gold for experienced surfers on a good reef. The period is long, so expect lulls between set waves, but the waves that come through will be proper.
There are no gaps, no flat spells – just a solid 16-day window of clean, strong SW groundswell at a world-class reef. The wind stays offshore or cross-off the whole time. If you can handle the size, this is as good as it gets.
Rusty.

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
